COVID-19
The global emergence of novel coronavirus disease 2019 (COVID-19) has underlined the requirement for rapid assays with high sensitivity and specificity for detection of infection and further to understand the molecular complexity of the disease.
Explore how our customers have used the Evosep One to develop an effective screening assay and comprehensive understanding of the disease.
the current situation for clinical proteomics
Professor Akhilesh Pandey now from the Mayo Clinic, Rochester, US talks with Nicolai Bache, Head of Applications at Evosep about the current situation for clinical proteomics and what is looming on the horizon.
With the ongoing COVID-19 pandemic the need for robust solutions for clinical proteomics are urgently required.
STANDARDIZATION IS KEY
The Evosep One serves as a robust and standardized front-end solution, which can be paired with the most widely used mass spectrometers. It allows for up to 300 samples analyzed per day and is therefore ideally suited for testing a large sample cohort with a specific clinical assay.
SENSITIVE AND SPECIFIC TARGETED ASSAY FOR DETECTION OF COVID-19
This publication describes the development of an automated antibody capture-based workflow coupled to a targeted FAIMS-PRM assay on an Orbitrap Exploris 480 MS developed by the Akhilesh Pandey group at the Mayo Clinic, Rochester, US from the analysis of more than 700 nasopharyngeal swab samples were analyzed.
The key advantage of the assay, which allows for 200 samples analyzed per day, is the high specificity and comparable sensitivity to the gold standard RT-PCR method for the diagnosis of SARS-CoV-2. The method can be adapted for detection of novel variants of SARS-CoV-2 as they appear and can easily be deployed at routine clinical laboratories with mass spectrometry instrumentation.
COMPREHENSIVE MULTI-OMICS UNDERSTANDING OF COVID-19
This publication from multiple research groups in Germany describes the molecular functions of viral proteins and their interactions with the host proteome of SARS-CoV-2. It serves as a resource describing the interplay between different omics levels.
The impact of viral infection on the proteome and phosphoproteome were analyzed in a time-resolved manner using the Evosep One with data-independent analysis on a Q Exactive HF-X. The analysis revealed key pathways perturbed during the infection identifying potential vulnerable points of SARS-CoV-2 that could be targeted by well-characterized selective drugs for antiviral therapies.
SERUM PROTEOMICS AND ANALYSIS OF RED BLOOD CELLS FROM COVID-19 PATIENTS
In these two studies, researchers from University of Colorado performed proteomics analysis of Covid-19 patients and healthy control individuals.
By using the Evosep One coupled to a timsTOF Pro, they measured the proteomes of red blood cells (RBC) and identified increased glycolysis in RBCs from COVID-19 patients, accompanied by increased oxidation of key structural proteins.
They also did a serum proteomics analysis stratified by the degree of inflammation, represented by IL-6 levels as a marker of disease severity. Their results highlight a clear increase in the levels of inhibitory components of the fibrinolytic cascade in severe COVID-19 disease, providing potential clues related to the etiology of coagulopathic complications in COVID-19 and paving the way for potential therapeutic interventions, such as the use of pro-fibrinolytic agents.
